Implement iterator::erase() in a simple version that erases nodes when they
become empty, but doesn't try to redistribute elements among siblings for better
packing.

Handle coalescing across leaf nodes which may require erasing entries.

Unittests need LLVM_BUILD_MODE to pick up each test.

Confirmed on CentOS5, Mingw, MSYS, and with possible configurations on VS8 and VS10.

by my recent GVN improvement.  Looking through a single layer of
PHI nodes when attempting to sink GEPs, we need to iteratively
look through arbitrary PHI nests.

situations where on the common path an API can return a pointer to some direct
memory, but which on an exceptional path may need to return a pointer to a
temporary struct.

I added these instructions recently but I have no idea where these "1"
values in the NextCycles field came from.  As far as I can tell now,
these instruction stages are clearly intended to overlap.

 - I'm leaving MachO.h, because I believe it has external consumers, but I would really like to eliminate it (we have stylistic disagreements with one another).

independent information on the Mach object format, and move some stuff from
MachObjectWriter.cpp there.

- Double the vector's capacity when growing to avoid unneeccesary reallocation.
- Do the reallocation with realloc(3) which can expand the memory in place.

GNU ld/PECOFF accepts but ignores them below;
  --version-script
  --export-dynamic
  --rpath

FIXME: autoconf should be aware of them.
